A few notes here: - Regulators are added directly to the board file. While it's true that this will mean a bunch of copy/pasting for other boards that are very similar, this is probably the right call since boards could make changes to the way these regulators are hooked up and trying to find a way to avoid duplication will result in some confusing node overrides. - Regulators that are hooked up to supply pins on the SoC are given an alias matching the name of that pin (pin name comes from the Qualcomm SoC "device specification" doc). - Other regulator labels are based on the schematic. If there is more than one logical name on the schematic for the same rail the secondary names are also listed and should be referred to as appropriate. - Regulators all default to HPM mode w/ no ability to switch modes. Future patches can switch things to LPM and possibly add dynamic load switching if we have determined there's a benefit. This should only be done for rails where we'll actually be able to take advantage of the lower power modes so we don't need to churn with lots of patches adding regulator_set_load() calls to drivers. NOTE: This patch is loosely based on one originally shared to me by David Collins. Signed-off-by: Douglas Anderson Reviewed-by: Stephen Boyd Reviewed-by: Bjorn Andersson --- Changes in v3: - Set vin-supply for s4a_1p8 properly (Stephen). - All regulators now HPM / disallow mode change; see commit text. - Added a few extra labels for some regulators. - Updated commit text descriptions. Changes in v2: - LDO14 initial mode is LPM and shouldn't be always on (Vivek G) - LDO25 should have min voltage of 3.3V arch/arm64/boot/dts/qcom/sdm845-mtp.dts | 321 ++++++++++++++++++++++++ 1 file changed, 321 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sdm845-mtp.dts b/arch/arm64/boot/dts/qcom/sdm845-mtp.dts index 6d651f314193..ef53c4ae60b0 100644 --- a/arch/arm64/boot/dts/qcom/sdm845-mtp.dts +++ b/arch/arm64/boot/dts/qcom/sdm845-mtp.dts @@ -7,6 +7,7 @@ /dts-v1/;
